12-second Editor-A low-energy particle data from the Geotail spacecraft.
Editor-A data are only acquired with the real-time operation in Usuda Deep Space Center (UDSC),Japan, while the Editor-B data are 24-hours continuouslyrecorded in the onboard tape recorders and are dumpedover the NASA/JPL Deep Space Network (DSN) stations.
The ion energy analyzer (LEP-EAi) has two energy scan mode: RAM-A (60 eV to 40 keV) and RAM-B (5 keV to 40 keV). RAM-B is selected to protect the very sensitive detector from intense low energy fluxes that are usually seen in the solar wind and magnetosheath. The energy scan mode is automatically selected onboard depending on incoming ion fluxes. At present, only the ion moments in the RAM-A mode are listed for the LEP-EAi data.
The ion moment data of the solar wind analyzer (LEP-SW) should be used only qualitatively. The LEP-SW ion moments are listed when the energy scan mode of LEP-EAi is RAM-B.Version:2.3.0

Data ARchives and Transmission System (DARTS) is a versatile space science data archive for astrophysics, solar physics, and solar-terrestrial physics. DARTS primarily consists of the data acquired by Japanese scientific satellites and spacecrafts. DARTS is developed and maintained by the Center of Science-satellite Operation and Data Archive (C-SODA) at ISAS/JAXA.
